Abstract: Abstract A railroad track curve is plotted by measuring ordinates at a fixed point of a fixed length reference line that is moved to a series of incremental points spaced around the curve, and the ordinates are stored in a data processor memory.  The data processor calculates theoretical ordinates for an ideal curve which most closely fits the measured ordinates, and the track is shifted at the incremental points under control of the processor a distance and direction corresponding to the deviation between the measured and calculated ordinates.  The system permits determination of transition points for simple and compound curves, and allows superelevation values to be selected and intermediate values calculated for smooth transition between tangent and constant curve track.  The reference line is established by a light beam, and the processor is part of a self-propelled, on-track lining machine.

Abstract: Abstract The rotary surface aeration device used to rotate and aera-te sewage is provided with a carrying part     connected to a vertically running drive axle     as well as with a plu-rality of liquid transporting units        fastened to the carrying part.     In order to improve the oxygen input, the liquid transpor-ting units       , which are adjacent to each other viewed in the circumferential direction of the rotary aerating de-vice,  have different jet exiting speeds. This is achieved by giving  the  scoop outlet edges         of  these  liquid transporting  units  which  are  adjacent  to  each other, a different distance        from the drive axle of  the  rotary  aeration  device.  The  liquid  transporting units    are  arranged and  constructed  in  such a way that the liquid jets of at least two liquid transporting units       , which are adjacent viewed in the circumferen-tial direction of the rotary aeration device, exiting from said  units  during  the  operation  of  the  rotary  aeration device strike each other before reentering into the liquid to be aerated.

Abstract: ABSTRACT OF THE DISCLOSURE            The invention relates to a method and a device for production of a temperature-stable, biaxially oriented container of thermoplastic material. In a first moulding stage a blank (40) is placed in a blow mould (12) after which a mandrel (15) extends the blank in its axial direction to a length exceeding the axial length of the future con-tainer. The length of the stretched material, in an axial section through the stretched blank, is then reduced at a predetermined temperature, and the reduction being made to a profile length sub-stantially agreeing with the profile length for corresponding mate-rial portions in an axial section through the future container. In a second moulding stage the stretched blank is expanded to abutment against the walls of the mould. The expansion takes place at a point in time for and/or at a speed allowing the reduction of the length of the stretched material to have time to be concluded before the mate-rial comes into contact with the walls of the mould.     Fig. 1 is proposed for possible publication.

Abstract: A B S T R A C T     A process for feeding metal to molten metal, in particular for the purpose of melting solid metal such as scrap metal or dross granules, is such that at least part of the melt is divided and each divided part set into motion rotating in  opposite  directions  so  that  at  least  two  rotating streams or "rolls" of molten metal are produced; the cen-tral axes of these rotating streams of molten metal form an angle. The metal is charged at the place where the two "rolls" of molten metal meet.     The "rolls" of molten metal are produced by introducing the molten metal into a pair of pipe lengths approximately perpendicular to their central axes and approximately tan-gentially to the cross section of the said pipe lengths, the central axes forming an angle, or by causing the mol-ten metal in the pipe lengths to rotate by means of elec-trodynamic forces.

Abstract: ABSTRACT      A process for adding calcium to a bath of molten ferrous material is disclosed in which a calcium metal-containing wire is fed through a refractory lance into the bath.  Recirculatory stirring of the molten ferrous material is accomplished with an inert gas flow through the lance.  The calcium-containing wire is fed at such a rate that it substantially bends towards the horizontal direction after it leaves the lance and melting of the calcium in the wire occurs primarily in or directly below a region of downwelling of the molten ferrous material.  Suitable wire feeding rates will depend upon the disposition of the lance in the bath and the composition (e.g. clad or unclad) and cross-sectional dimensions of the calcium metal-containing wire.

Abstract: ABSTRACT:          Hybrid loudspeaker system, at option with one or more correction circuits.        In a loudspeaker system for converting an n-bit digitized electric signal (6) into an acoustic signal a plurality of sections (voice coils 14.1 14.2, 14.3, 14.p) of a digital loudspeaker (1) are driven directly by the p most significant bits of the n-bit digitized electric signal (6). The loudspeaker (1) comprises at least one additional section (14.p+1). This (p+1)th voice coil receives a signal from a digital-to-analog converter (5), the input signal of the digilal-to-analog converter com-prising at least the n-p least significant bits (Fig. 2).          In a different embodiment the digital-to-analog converter (5) receives all the n bits of the digitized electric signal as the input signal. At least the p sections (14.1 to 14.p) which correspond to the p most significant bits are provided with means (the resistances r) for producing a signal which is a measure of the sum of their instantaneous drive signals and for applying the said signal to a signal combination unit (32) arranged in the line (10) from the output of the digital-to-analog con-verter (5) to the (p+1)th section (R1). By means of this correction circuit the distortion in the loudspeaker system can be reduced substantially (Fig. 3b).

A random access memory (RAM) stores a copy of the defective sector logs.  During a seek operation, firmware tests the defective sector log in RAM to generate the alternate sector log for that cylinder number.  During the read or write operation, the alternate sector  log  is  checked before processing the sector to determine if it is a defective sector.  If the sector is defective, the head is positioned to another cylinder at a head and sector address read from the alternate sector log.
